"Περσών" refers to the ancient civilization of the Persians, who established one of the largest empires in history, known as the Achaemenid Empire. This empire, which flourished from the 6th to the 4th century BCE, was known for its remarkable administrative system, cultural diversity, and architectural achievements, including the famous city of Persepolis. The Persians were known for their contributions to art, science, and governance. They developed a complex road system, the Royal Road, which facilitated trade and communication across their vast territories. The empire eventually fell to Alexander the Great in the 4th century BCE, marking the end of Persian dominance in the region.
